We present results on the fragmentation of singly and doubly charged adenine induced by electronic capture processes in collisions with 6 keV F 2+ projectile ions. The results are compared to our previous study at 36 keV collision energy. In these ex

Doubly excited ions have been obtained in one-electron capture processes by metastable ions from Cs (6s). Incident heliumlike ions have been prepared in high metastable fractions by collision in a gas cell of hydrogenlike ions produced by an ECR ion

We present the observation of VUV transitions between doubly excited states of Ne7+. Spectra were selectively produced by single electron capture in a cesium vapor by Ne8+ ions prepared in the metastable state 1s2s 3S by a previous collision of a Ne9

Optical spectroscopy has been used to study electron capture into Ar{sup 9+} and Ar{sup 8+} ions from cesium at several impact energies of between 8 and 180 keV. Many Rydberg lines were observed. At high spectral resolution the quasi-{ital l}-degener

We have measured the wavelengths of the 1s2s3S1-1s2p3P2 transition in heliumlike Xe L III and the 1s22s2S1/2-1s22p2P1/2,3/2 transitions in lithiumlike Xe L II. The measurements were made at GANIL by bean-foil spectroscopy of xenon at 27 MeV/u. The wa

We present an analysis of our wavelength measurements for the 1s2s 3S1-1s2p 3P2 transition of Fe XXV in beam-foil excited spectra at 6 MeV/u and 7 MeV/u. Results are compared with calculations including the non-relativistic energy, the one-electron D

The impact of highly charged and high energy ions in a gas target produces excited recoil-ions. The speed of these ions being quite low, the Doppler shifts and broadening of emitted lines are very small. With a Kr20+ beam at 1.15 MeV/amu, we have obs
